Configuration Register (CONFIG)
3.1 Introduction
This section describes the configuration registers, CONFIG1 and CONFIG2.
The configuration registers enable or disable these options:
Computer operating properly module (COP)
COP timeout period (2

CGMXCLK cycles)
Crystal oscillators during stop mode
Low voltage inhibit (LVI) module power
LVI module reset
LVI module in stop mode
LVI module voltage trip point selection
STOP instruction
Stop mode recovery time (32
or 4096
CGMXCLK cycles)
LCD frontplanes FP3–FP10 on port E
LCD frontplanes FP11–FP18 on port D
